Question

以下是我的applicationContext.xml

<bean
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="entityManagerFactory2">
    <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.m3.xml" />
    <property name="persistenceUnitName" value="M3tables" />
    <property name="packagesToScan" value="com.foo.webapp.integration.model.m3" />
</bean>

<bean
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="entityManagerFactory1">
    <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml" />
    <property name="persistenceUnitName" value="webApp-integration" />
    <property name="packagesToScan" value="com.foo.webapp.integration.model.test" />
</bean>
<!-- ##################################### -->

<!-- Transaction Manager -->
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager1">
    <property name="entityManagerFactory" ref="entityManagerFactory1" />
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager2">
    <property name="entityManagerFactory" ref="entityManagerFactory2" />
</bean>
<tx:annotation-driven mode="aspectj"
    transaction-manager="transactionManager1" />
<tx:annotation-driven mode="aspectj"
    transaction-manager="transactionManager2" />

<jpa:repositories base-package="com.foo.webapp.test.repository"
    entity-manager-factory-ref="entityManagerFactory1" />

<jpa:repositories base-package="com.foo.webapp.repository"
    entity-manager-factory-ref="entityManagerFactory2" />

在我的服务文件中，我以两种方式添加了事务管理器

1。通过在课程级别添加

@Service
@Transactional(value="transactionManager2")
public class MitmasServiceImpl implements MitmasService {
    @Override
    public List<Mitmas> getAllItem() 
    {
        return mitmasRepository.findAll();

    }
}

通过在方法级别添加事务

@Service
public class MitmasServiceImpl implements MitmasService 
{
    @Override
    @Transactional(value="transactionManager2")
    public List<Mitmas> getAllItem() 
    {
        return mitmasRepository.findAll();

    }
}

我的完整服务文件位于

@Service
@Transactional(value="transactionManager2")
public class MitmasServiceImpl implements MitmasService {

    @Autowired
    private MitmasRepository mitmasRepository ;

    @Override
    @Transactional(value="transactionManager2")
    public Mitmas createItem(Mitmas Mitmas) 
    {
        return mitmasRepository.save(Mitmas);
    }

    @Override
    @Transactional(value="transactionManager2",rollbackFor=ItemNotFound.class)
    public Mitmas deleteItem(String itemNo) throws ItemNotFound 
    {
        Mitmas deleteItem = mitmasRepository.findOne(itemNo);
        if(deleteItem == null)
        {
            throw new ItemNotFound();
        }
        else
        {
            mitmasRepository.delete(itemNo);
        }
        return deleteItem;
    }

    @Override
    @Transactional(value="transactionManager2",rollbackFor=ItemNotFound.class)
    public Mitmas updateItem(Mitmas Mitmas) throws ItemNotFound 
    {   
        Mitmas updateItem = mitmasRepository.findOne(Mitmas.getMmitno());

        if(updateItem==null)
        {
            throw new ItemNotFound() ;
        }

        updateItem.setMmitds(Mitmas.getMmitds());
        updateItem.setMmfuds(Mitmas.getMmfuds());

        return updateItem;
    }


    @Override
    @Transactional(value="transactionManager2")
    public List<Mitmas> getAllItem() 
    {
        return mitmasRepository.findAll();

    }


}

但我收到了以下错误

任何人都可以帮我解决这个问题

Answer 1

如前所述，您正在使用Spring Data JPA和多个EntityManagerFactory bean。您需要告诉Spring Data JPA EntityManagerFactory和PlatformTransactionManager用于该特定配置。如果您未指定，则尝试使用默认transactionManager。这在Spring Data JPA参考指南中解释为here。

请注意，如果未定义明确的PlatformTransactionManager，我们需要一个名为transactionManager的{{1}} bean。

您的配置

transaction-manager-ref

您只指定了<jpa:repositories base-package="com.foo.webapp.test.repository" entity-manager-factory-ref="entityManagerFactory1" /> <jpa:repositories base-package="com.foo.webapp.repository" entity-manager-factory-ref="entityManagerFactory2" />而不是entity-manager-factory-ref，因此它会尝试找到名为transaction-manager-ref的{{1}}。

要修复，请在元素中添加相应的PlatformTransactionManager。

transactionManager

org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为'transactionManager'的bean @Spring + JPA
